IMPROVEMENT IN GANG-PLows.

Specification forming part of Letters Patent No. 153,037, dated July 14, 1874; application filed May 12, 1874.

To all whom it may concern:

Be it known that I, WILLIAM O. M. BERRY, of San Francisco city and county, State of California, have invented an Improved Gangllow; and I do hereby declare the following description and accompanying drawings are sufficient to enable any person skilled in the art or science to which it most nearly appertains to make and use my said invention without further invention or experiment.

My invention relates to that class of gangplows in which .two or more plows, similar to single plows, are suspended below the axle of a two-wheeled vehicle or sulky, and operated by a driver' mounted upon the vehicle.

teferring to the following specification and accompanying drawing for a complete description of my improvements, Figure l is a plan or top view. Fig. 2 is a perspective view. Fig. 3 is an enlarged section.

A A are two wheels, secured to the opposite ends of thc axle B. C is a platform, upon which the drivcrs seat D is mounted. E is the pole or tongue of the vehicle, which is secured upon the axle B near one end and at 011e side ofthe platform C, for the purpose hereinafter described. F F F are three plows, each of which has a curved metal standard, G. rIhe first part of my invention relates to the manner of connecting these plows together so that they can be detached from one another for thc purpose of converting the plow into a two-gang plow, or into a sulky single plow, as may be desired. rIhe beam H of the plow F is a continuation of its curved standard G. The beam H of the sccond plow F has a rear extension, I, which is bent at a proper angle to the beam to preserve the parallelism of the beams H H', and its extremity is bolted or otherwise secured to the rear end of the beam H. The upper end of the curved standard G ofthe plow F is then bolted or otherwise secured to the rear end of the beam H. The beam H of the third plow F is continuous with its curved standard, and its forward end is bolted to the forward end of the beam H of the second or middle plow. rJlhe beam is then bent so as to give the required distance between the plows, and a metallicbrace, J, has its opposite ends bolted to the rear ends ofthe beams, thus connecting the plows and plow-beains together by means of bolts, which may be removed to separate the parts, and providing, when bolted together, a strong combination of beams and braces. A metallic tube, K, is secured in a vertical hole which passes through the tongue or pole E of the vehicle a short distance in front of the axle. A tube or rod, L, passes down through the tube K, and has secured to its lower end a short horizontal or transverse tube, fm, thus forming an inverted T. The forward ends of the plowbeams H H are connected together by a rod, n, which passes through the horizontal tube m. 0 is a cranklever, having its angle pivoted to the axle inside of the pole E. A rod, p, connects the short arm of this lever with the horizontal tube m, so that it can be raised and lowered by moving the lever back and forth, the vertical tube or rod L serving as a guide by moving through the bushing or extended bearing K. This vertical adjustment of the forward end of the beam H will Aslightly elevate the points ofthe plows, so as to run them deeper or more shallow, as desired. The rear ends of the series of plows a-re supported by a chain, q, whichl connects them with the short arm of a lever, It. IVhcn this lever is thrown ldown upon the tongue E and secured by the catch S, the plows will be supported above the ground.

It will be seen that as the pole E is secured upon the axle near one end, the moldboard of the outside or first plow F will extend outside of the wheel, so that both wheels of the vehicle will run upon the unplowed ground. A short chain, t, is suspended from the under side of the pole E in advance of the forward ends of the plow-beams, and other chains, u a, connect the lower end of this chain with the forward ends of the plow-beams H H. rlhe whiftletrees will be attached at the julietion of the three chains, so as to apply the draft directly to the plows. The rod oz., which connects the forward ends of the plow-beams, is adjustable in the horizontal tube m, so as to change the draft of the plows, and is secured at the desired point by a set-screw, V. The length of the chains a can be allowed to suit the change of draft by taking up or letting out a link, as desired.

By this construction and arrun gementI pro- L and tube K, with its horizontal tube n, crankvide a simple, cheap, and extremely useful lever O, and connecting-rod p, substantially as plow, which can be used as a sulky-plow, a and for the purpose above described.

two-gang plow, or 2t three-gang plow. In witness whereof I hereunto set my hand Having thus described my invention, what I and seal. claim, end desire to secure by Letters Patent, 4W'ILLIAM O. M. BERRY. [L S.] is- Witnesses:
